l HENRY IN'OAEK AND SAMUEL C. DUKE, OF WALLER, TEXAS.

VENDING-MACHINE.

Application filed October 26,1915. Serial No. 57,931.

To all whomz't may concern: I

- Be it known that we, Hnnnr NoAnK and SAMUEL C. Dun-E, citizens of the "United States, residing at NValler, in the county of Waller and State of Texas, have invented certain new and useful Improvements in a device of the character described 'a dapted for the purpose of vending liquids such as gasolene, oils andthe like. Another object of the invention resides in the construction whereby a fixed value of the commodity will be delivered to the purchaser, the construction being so arranged that the quantity delivered may be varied in accordance with variation in prices. I A further feature of the invention resides in the provision of a register wherebythe value of the entire quantity "delivered will be indicated.

A still further feature of the invention resides in the provision of a mechanism whereby different quantities of the commodity may be delivered in accordance with the amount desired; and the invention also comprehends a construction whereby spurious coins when inserted will be thrown out without tripping the operative mechanism and. causing a delivery.

lVith the aboveand other objects in view the invention has particular relation to -certain novel features of construction, opera tion and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings wherein;

cylindricalin form and which contain the commodity to be sold. An auxiliary container 5 is provided which is connected to the container 2 through the pipe 6. This last mentioned container may of course be dispensed with and is provided only for the purpose of increasing, in effect, the capacity An inlet pipe 7 leads from a suitable source of supply and communicates with said containers through which they are supplied with the liquid and leading from said container is the discharge pipe 8. These pipes are controlled by suit? able two Way valves 9, 10 and 11 respectively of the ordinary construction which it is not thought necessary to specifically describe, said valves being controlled through the transverse shafts 12, 13 and 14 respectively,

'as will hereinafter be explained so that when free ends of these arms the respective'links 18, 19} and 20 are pivoted at one end and to the other ends of these links the respective rods 21, 22 and 23 are adjustably secured. These rods are slidable through the coin block 24 which is slidable on a track formed of the rods 25 and 26 whose respective ends the coin chutes 2,7, 28 and 29 extending vertically therethrough, of-diiferent dimensions so as to receive coins of different sizes in accordance with the amount ofthe commodity which it is desired to purchase. These chutes areal-ranged in alinement with the respective rods 21, 22 and 23.

Underneath the coin block are the receptacles 30. and 31 provided to receive the gen nine and spurious coins respectively. In 'case a certain quantity of the commodity s desired a coin-of the proper size. will he in- 1 serted, for example, in the chute 2 and said This block has a coin, which is indicated by the numeral 32 will drop down behind the enlarged head carried by the inner end of the rod 21 and the handle 33 carried by the coin block 2 1 may thenbeforced forwardly and said coin will lock against the end ofsaid rod 21 and operating through the link 18 and the arm will cause the shaft 12 to turn manipulatel'ted through the rod 21, the link 18 and the arm 15 will operate to again manipulate the valve 9 in the reverse direction to open the inlet and close the discharge pipe and the. container 2 will again fill with the liquid. If coins are not inserted in the chutes 28 and 29, during this operatioh just described, the rods 22 ,and will remain stationary, the block 21 sliding thereon and their enlarged heads passing through the passage ways as in said block alinement therewith. Should coins be, inserted in all of the chutes at the same tim and the block 24 forced forwardly on its track all of the valves 9, 10 and 11 will bemanipulatd and tlie'total amount of the liquid in the-containers 2, 3 and a will be delivered. The enlarged heads of the rods21, 22 and 23 are arranged to en,- gage with. the block 24 so that when it is moved back to its original position they will not disengage therefrom.

In case a coin smaller than that required is inserted in any slot it will drop on {down through the alined-slots 35, 36 or 37, as the case may be, out through the transverse partition 38 forming the top of the coin; re-

ceptacles and may he recovered, but when a the proper sized coin is inserted it will lock against the enlarged head of the corresponding rod and willpbe carried forwardly.

When the movement of the block 2 1is reversed it will operate to slightly release the coin and when the same passes over tln? alined slot 38, 39 or 40,.as thec ase may be, it will drop through said slotinto the closed receptacle 30. Diverging froinithe respec tive chutes 27, 28 and 29 'arethe chutes '11, 12 and 13 provided for the. passage wayv of spurious coins and at the entrance of the chutes on thehsides from which the spurious coin chutes diverge are the magnets 44,

and 16. Spurious coins are usually formed of metal whlch is attracted by a magnet and when spuriousfcoins of this character are inserted they will, by said magnets, be directed down the spurious coin" chutes, and will pass through the slots 47, as or 19, as the case may be, out through the partition 38, and will fall into the spurious coin receptacle 31. I

Eaph of the containers is provided with ,a plungeras connected to which is'a hollow ing box 52 carried by thecontainer head'and shaft as 51 which passes through the stuffthis plunger is'manipulatedup and down so bracket '54 and through whiclnthe 'externally threaded portion of the shaft 51 passes. The upper end of each shaft 51 carries a cyllnder 55 having the seat 56 therein which is normally closed by the valve 57.

This valve seats upon the vcoil spring 58 whereby it is held closed. Upstanding from the valve 57 is the stem 59 which passes through the stufiing box 60 inthe. upper end of the cylinder 55. The said upper end of said cylinder has a plurality of orifices 61 to admit air for a purpose to be hereinafter explained. Slidably mounted in vertically alined bearings is the rod 62 whose upper end carries a .laterally extended arm 133 alined over the stem 59 and the lower'end of this red is turned atright angles forming a hook as 64. The corresponding ends of the shafts 12, 13 and 14 have arms as (35 fixed thereon and when either of said shafts is turned, as hereinbefore explained, to effect a delivery of the liquid, its arm 65 will engage with the corresponding hook 4 and exert a downward pull on the rod 62 bringing the arm 63 into contact with the upper endgoct' the stem 59 and thereby unseating the valve 57 whereby air is admitted to the corresponding container to prevent the for- -mat1on of a vacuum therein.

This rod 62 is normally held elevated through a pull spring, .one end of which is attached thereto and the other'end of which is securedto the stationary bar 66. As will be observed from an inspection of'Fig. '1 each of the shafts '51 is provided witha gage and a slidable hand as (37, by the movement of which relative to the gage, the price of the commodit may be indicated.

A registering device hasb'eenprovided to indicate the value of the commodity deliv-s ercd from each of the containers, this device 7 being shown in detail in Figs. 5, 6 and 7, which will now be described. Attached to the front side of the container is a circular casing 68' havingan oblon slot .69 out therethrough and a central sl d i ft 70 is rovided whereon is rotatable the spurgear 1 which is integral with the annular disk 72 being connected tliereto through the neck73, This neck forms a bearing for the independently rotatable annular disk 74 whose periphery is serrated and th isidisk has the numerals 5 and multiples thereof to 95 indicated thereon w ich pass under the outer end of the slot 9 as'the disk 74 rotates. The corresponding face of the disk 7 2 has the numerals from 1 thereof in a manner the reverse of the ar 'rangement of l to 19' inclusive arranged around the rim I messes said last mentioned numerals passing under the inner end of the slot 69. An idle gear wheel 75 is rotatably mounted upon the casingwall and in mesh with the gear Wheel 71. The rear face of the disk 74 carries a pin 76 arranged to contact with and impart a partial rotation to the ear Wheel 75 With each rotation of the disk 4. As shown When one dollars worth of the commodity has been sold the disk 74: will have made one rotation causing a partial rotation of the disk 72 and bringing the numerals l to 9 successivel into view through the slot 69, said numera s denoting the number of dollars Which have been deposited in the coin receptacle. lhe disk M is rotated through a flexible finger 77, the lower end of which is attached to one side of the corresponding shaft 12, 13 or 14 and the upper end of which is held in engagement with the peripheral teeth of the disk 74: through the pull spring 78, one end cl which is attached to said finger and the other end of which is secured to the casing 68. As the corresponding shaft is turned to open the valve and deliver the commodity an upward thrust is imparted to the finger it? causinga partial turn of the disk 74. This disk is held against reverse movement by means of a flexible spring 79, one end of which is attached to the casing 68 and the free end of which engages against the abrupt sides of said peripheral teeth. The marginal numerals on the disk 74 will, of course, vary in some cases quantities of the value of five cents will be sold and in other cases twenty five cent or fifty cent quantities only will he sold and said numerals should be varied accordingly While We have shown only one form of this device it is obvious that the mechanical structure thereof may be varied without departing from the principle of the invention and we hereby reserve the right to make such. structural changes as may be found necessary so long as we keep within the scope of the appended claims.

W hat we claim is:

1. In a device of the character described, an actuating mechanism, a coin block slid ably mounted and ha ring a coinchute therein and operativcl'y connected with said mechanism through the coin deposited in said chute, said block also having a diverting chute through which spurious, coins may pass without bringing the block into opera tive connection with said mechanism.

2. A device of the character described embod'ying a plurality of actuating mecha nisms, a manually movable means havin a plurality of coin chutes therein and which is operatively connected with the corre sponding mechanics through the coin placed in the chute corresponding? to said mechanism" to be operated and an indicat ing device actuated through'said mechanism and indicaisirs the denomination of the coin deposited in thecorresponding chute.

3. Pl valveoperating mechanism embody ing a slidahly mounted block having a coin chute therein, an operating rod, one end of which projects through said hloclr hut which is locked against movement relative to the block by means of the coin placed in said chute, said block also having a divertingchute through which spurious coins may pass without bringing the hi air into opera tive connection with said rod 4. A'valve operating mechanism embodying an operating rod, a means slidahly mounted on said rod and having a coin chute provided to receive a coin which locks said means against movement relative to the rod, and also having a coin diverting chute through which spurious coins may pass without locking said means against movement relative to the rod.
